SUMMARIZE IN ONE SENTENCE The truth about pigs is that their reputation for being dull and dirty is undeserved. The pig is actually a curious and intelligent animal. For instance, a pig will not take anything for granted; it will poke, and prod something until it arrives at a conclusion. A pig's intelligence is so keen that the animal needs to do something only once – such as turn on an automatic drinking fountain – to know how to do it again. Furthermore, pigs are basically no dirtier than any other farm animal. Because pigs don't sweat, they seek out water in order to cool off. On a farm, the water that a pig finds is usually in a mud puddle. However, the pig would be just as happy splashing in a bathtub since it is water, not dirt that pigs enjoy.​

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
